Greenlet runtime error and deployed app in docker keeps booting all the workers

Question

RuntimeWarning: greenlet.greenlet size changed, may indicate binary incompatibility. Expected 144 from C header, got 152 from PyObject

And all the workers are being booted.

It was working fine about a week ago, and now I'm having problems.

Answer 1

This is a warning message indicating that there may be a compatibility issue between different versions of the "greenlet" library. The warning message is indicating that the size of the "greenlet" object has changed, and that the expected size (144 bytes) does not match the actual size (152 bytes). This could cause problems in code that relies on the expected size, so it's a good idea to investigate the source of the compatibility issue.
